Özet

Partitioning of semi-volatile organic compounds (SOCs) between the gas and suspended particle phase plays an important role in determining their atmospheric fate and transport. Knowledge of the fate and transport of polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) is valuable in defining their beneficial or deleterious effects to the environment. A modified high-volume sampler (PS-l) was used to determine the gas-particle distribution of PAHs and PCBs. The particle phase fraction of low molecular weight PAHs were higher than those predicted by Junge-Pankow model. Whereas the values for high molecular weight PAHs were overestimated by the model. Plots of log K-p vs. Log P-L(0) show the partitioning of PAHs and PCBs are not at equilibrium.
